3.2Console Mounting of Remotes.

If optional Cat. No. 428 remote housings (holding up to three remote control units each) are not used, the remote controls can be placed in spare sections of the console. The size of each remote unit is 150 mm x 39 mm with a maximum projection behind the control surface of 100 mm. The shielded cable connecting them to the main control unit can run in any convenient trunking to the console although trunking which carries high level signals is preferred. The short link between the remote contol units is unshielded ribbon cable and carries a low level waveform which can radiate interference into mixing busses and microphone inputs if held very close to them. These facts should be kept in mind when selecting suitable sites for the remotes. If blanking panels are available, these can be cut with a slot to mount the remote control modules.

3.3Channel Number Assignment

As in any bussed system each element of the system has an address. To determine its address, the Cat. No. 413 suppressor module has to be withdrawn from the chassis. The two front panel knurled screws which hold the module in the frame should be loosened and the module withdrawn using the handle. At the back right-hand side of the printed circuit board is a rotary switch with either a pointer pointing towards a number printed on the switch or a slot in the top with a number showing. This number is the address of the module. Normally the upper module in the rack is given the lowest address so the switch in this module should be set to “1”; the next module’s switch should be set to “2” and so on. Similarly the remote control modules have addresses. The rotary switch which sets it can be seen through a hole in the back cover of each remote module. The positions of the switches should match the addresses of the Cat. No. 413’s they control so channel 1’s remote should have the address switch pointing to channel 1, etc. Selection requires a small screwdriver to rotate the switch to the required channel. Note switch positions 0, 7, 8 and 9 are not used.

If the optional Cat. No. 428 remote control housing is used, the base must be removed by unscrewing the six screws on either side of the housing. When the base is slid off, the backs of the remote modules are exposed.
